Embodiment
In order to make those skilled in the art more fully understand technical scheme, below in conjunction with attached drawing to this hair
It is bright to be further detailed.
As shown in Figs. 1-3, the embodiment of the present invention provides a kind of double-clutch automatic gearbox, it includes gear box casing, peace
Loaded on the tooth shaft mechanism 11 in transmission housing body, tooth shaft mechanism 11 includes synchronizer, and is fixed on same in transmission housing body
Walk device lubricating structure.Gear box casing is the installation of whole double-clutch automatic gearbox, brace foundation, tooth shaft mechanism 11 for it is double from
The power part of automatic transmission is closed, it includes axis and the gear being installed on axis, synchronizer etc., and synchronizer lubricating machine
Structure is then the increased part of the embodiment of the present invention, which is used to carry out lubrication assistant to synchronizer, it can specifically pass through screw thread
Fastener is fixed in transmission housing body.
Above-mentioned synchronizer lubricating structure includes lubrication shell 12, on the lubrication shell 12 there is lubricating oil collecting chamber and lubricating oil to go out
Mouthful.Lubricating oil collecting chamber is connected with lubricating oil outlet, it can use open architecture, can be held with the lubricating oil that this ensures to splash
Change places and flow into the lubricating oil collecting chamber.Lubricating oil outlet can only be arranged to one, along vertical direction, lubricating oil outlet with it is same
Position where walking device is opposite, after so can ensureing outflow of lubrication oil lubricating oil outlet, can be dripped under the action of self gravitation
Drop down onto on synchronizer.
During using above-mentioned double-clutch automatic gearbox, since synchronizer therein is using the mode of splash lubrication, because
This lubricating oil to splash will enter in lubricating oil collecting chamber, and the lubricating oil after collecting is reached by lubricating oil outlet where synchronizer
Position so as to synchronizer carry out lubrication assistant.Obviously, compared to the content described in background technology, above-mentioned double clutches
Automatic transmission collects original lubricating oil in transmission housing body by lubricating shell 12, and this parts of lubricating oil is guided to again
At synchronizer, recycling for lubricating oil is realized with this, and need not ensure the lubricant effect of synchronizer using more lubricating oil.
Therefore, the oil consumption of double-clutch automatic gearbox provided in an embodiment of the present invention is relatively low.
In view of synchronizer has larger volume in itself, therefore in order to improve the lubricating uniform of synchronizer, the present invention is real
Apply example and lubricating oil outlet is arranged to multiple, each lubricating oil outlet is spaced apart on lubrication shell 12.Specifically, each lubricating oil goes out
The distributing position of mouth is determined according to the specification of synchronizer, can equably be covered together with the lubricating oil flowed out in each lubricating oil outlet
On the basis of step device.As shown in Fig. 2, lubricating oil outlet can be four, it is specially first outlet 13, second outlet 14 and the 3rd
Outlet 15, the shape and size of each lubricating oil outlet are flexibly set according to demand.
When the lubrication of synchronizer is realized by the way of splash lubrication, the direction of motion of lubricating oil is usually more at random, this
A part in a little lubricating oil can enter lubricating oil collecting chamber, and another part still can splash in transmission housing body, and
Lubrication assistant effectively can not be carried out to synchronizer.To make more lubricating oil enter in lubricating oil collecting chamber, above-mentioned synchronizer
Lubricating structure further includes the guiding rib 16 being arranged on lubrication shell 12, which protrudes relative to the surface of lubrication shell 12,
And one end of guiding rib 16 is extended at the position where lubricating oil outlet.After above-mentioned guiding rib 16 is set, whole synchronizer profit
Stop area of the sliding mechanism to lubricating oil increased, and then object defined above.Also, above-mentioned guiding rib 16 can also be to profit
Lubricating oil in lubricating oil collecting chamber plays guide functions so that lubricating oil can quickly and accurately be flowed by lubricating oil outlet
To synchronizer.
One end of above-mentioned guiding rib 16 can be extended only near lubricating oil outlet, further, one end of guiding rib 16
Extend at the inner wall of lubricating oil outlet, the connection of guiding rib 16 and lubricating oil outlet is realized with this, more greatly increase stream
Enter the lubricants capacity in lubricating oil outlet, improve the lubricant effect of synchronizer.In addition, above-mentioned guiding rib 16 can only be arranged to one
It is a, it may be alternatively provided as two or more.When guiding rib 16 is two or more, each guiding rib 16 can be with lubrication
Radially arrange centered on oil export, and then strengthen the lubricant effect of synchronizer.With reference to Fig. 2, guiding rib 16 is two, this two
A guiding rib 16 can form v-shaped structure.
Alternatively, synchronizer lubricating structure provided in an embodiment of the present invention may also include multiple be fixed on lubrication shell 12
Positioning pin, lubrication shell 12 are installed on gear box casing by each positioning pin.With reference to Fig. 2, positioning pin specifically may be configured as four,
Respectively the first positioning pin 17, the second positioning pin 18, the 3rd positioning pin 19 and the 4th positioning pin 20, this four positioning pins are distributed in
In the outer rim for lubricating shell 12.Compared to threaded fastener, the fixation of lubrication shell 12 is realized using positioning pin, lubrication shell 12 can be simplified
Disassembling operations, reduce lubrication shell 12 dismounting cost.
In double-clutch automatic gearbox provided in an embodiment of the present invention, each gear in tooth shaft mechanism 11 usually has not
Same outside diameter so that whole tooth shaft mechanism 11 is in rough structure.In order to adapt to this structure, while improve double clutches certainly
The compact-sized degree of dynamic speed changer, reduce the distance between lubricating oil outlet and synchronizer, and above-mentioned lubrication shell 12 may include multiple
Sequentially connected arc shell, each arc shell phase have the radial dimension not waited for the axle center of tooth shaft mechanism 11, and in vertical side
Upwards：Each arc shell is opposite with multiple gears in tooth shaft mechanism 11, has anti-interference between arc shell and corresponding gear
Gap.Anti-interference gap herein can set smaller as far as possible, prevent from interfering between lubrication shell 12 and gear with this
In the case of, lubrication the distance between shell 12 and gear are reduced, so as to reach object defined above.It should be noted that above-mentioned radial ruler
In the same axial cross section of the very little axis in tooth shaft mechanism 11 that refers to arc shell, along size possessed by the axial direction of axis.
Based on said structure, the embodiment of the present invention also provides a kind of automobile, which includes any of the above-described technical solution institute
The double-clutch automatic gearbox of description.Since above-mentioned double-clutch automatic gearbox has above-mentioned technique effect, this pair of clutch is included
The automobile of automatic transmission should also have corresponding technique effect, and details are not described herein again.
Some one exemplary embodiments that only the invention has been described by way of explanation above, undoubtedly, for ability
The those of ordinary skill in domain, without departing from the spirit and scope of the present invention, can be with a variety of modes to institute
The embodiment of description is modified.Therefore, above-mentioned attached drawing and description are regarded as illustrative in nature, and should not be construed as to the present invention
The limitation of claims.
